The LDS website advises 60 lb of sugar and sweetners such as honey and molasses. They only advise 8 lb of salt.
I keep about 8 lb of table salt and a little sea salt on hand. However I keep at least 5 boxes of canning and a couple of boxes of rock salt on hand too.
I didn’t use as many this year as usual though, because I had very little produce to put away. The drought really cut down on my produce from the garden.
We usually make a big batch of ice cream a couple of times a year in the summer. Also when the kids want a treat I make a batch just using a couple of zip lock bags, some crushed ice, and a little rock salt. Ready in about 20 minutes or so. Dairy Queen consistency.
